Same, I was expecting some kind of statistical analysis along the lines of the birthday paradox.

It’s in German, but here’s open data about dog names in the city of Zürich:

The CSV should be clear enough:

So German cities have employees /systems whose job it is to register dog names not totally sure that's the best use of taxpayers money - better bike lanes and electric charging infrastructure or even GASP better support for homeless people.

Worth noting: Switzerland has a pet tax, so that obviously pays for it.

It is, the data also includes owner information so lost pets can be returned to their owners.
